Title: Method and apparatus for preventing overflow and underflow of an encoder buffer in a video compression system
Inventor: AUYEUNG CHEUNG
IPC: H04N21/234
Filed: 1995-12-14
Granted: 2000-08-08
Abstract: The present invention is a method and apparatus for preventing overflow and underflow of an encoder buffer in a video compression system. A virtual buffer is created in a rate controller to model the decoder buffer fullness (102). A sequence of bits is generated by an encoder (104). The encoder is controlled by the rate controller to prevent a decoder buffer underflow and overflow. Then, the sequence of bits is received by the encoder buffer to produce a bitstream (106). The bitstream corresponds to an instantaneous channel bitrate. The bitstream is transmitted from the encoder buffer to a decoder buffer following a delay (108). The delay is controlled by a rate controller to synchronize an encoder buffer fullness with a virtual buffer fullness (110). The synchronization prevents overflow and underflow of the encoder buffer.

Title: Subglobal area addressing for electronic price displays
Inventor: BRIECHLE GEORGE T
IPC: G06Q30/00
Filed: 1997-06-25
Granted: 2000-02-01
Abstract: An electronic price display system has uniquely addressed electronic shelf labels (ESLs) controlled by a central computer or host.  To save power and communications channel bandwidth, subglobal addressing is defined which permits the central computer to address more than one but less than all of the labels.  In one application of the addressing protocol the central computer causes the subglobally addressed labels to perform some common action such as changing a display to an alternative display.  In another application of the addressing protocol the central computer uses the subglobal addressing to disambiguate when data collisions occur due to more than one label attempting to respond to a global query.

Abstract: A system for restricting access to transmitted programming content is disclosed, which transmits the encryption key used to encrypt the program to the customer with the encrypted programming content. A set-top terminal or similar mechanism restricts access to the transmitted multimedia information using stored decryption keys. The set-top terminal preferably receives one or more package keys, SJ, periodically from the service provider, each corresponding to a package of programs that the customer is entitled to for a given period. Each program is preferably encrypted by the head-end server prior to transmission using a program key, KP, which may be unique to the program. Header information is transmitted with the encrypted program to the customers, containing a package pair for each package to which the program belongs. A package pair preferably includes an identifier of the package, as well as the program key, KP, encrypted by the corresponding package key, SJ. The broadcast of a given program, p, preferably consists of a header portion containing a package pair for each package that the program belongs to, and a program portion containing the program encrypted with the program key, KP. If a customer is entitled to a particular program, the set-top terminal will be able to decrypt the encrypted program key, KP, using an appropriate stored package key, SJ, and thereafter use the program key, KP, to decrypt the encrypted program. The header information can be interleaved with the program portion or transmitted on a separate dedicated control channel.

Abstract: A controller stores image signals Sp represented as binary values for every unit of frame. The controller divides one frame into a plurality of sub-frames representing an image by image data of two gradation levels, in accordance with respective figures of the stored image signals Sp for one frame.      The image data of two gradation levels for each of the sub-frames is written into capacitors Cp from a drain driver, for every row. When the image data is "1", a drive transistor is turned on. A common driver applies a voltage of a predetermined level for every sub-frame, to control the voltage applied between.electrodes of an organic EL element. As a result, the organic EL element emit light with brightness which differs between sub-frames. Images of the sub-frames are visually synthesized, so that gradation is expressed in one frame.

Abstract: In the manufacture of multichamber tubular containers it has been found that the inner divider walls (12) should be bonded to the exterior wall (10) by means of a band sealing method. In the band sealing method there is a band (30) that contacts the upper film and a band (32) that contacts the lower film that are to be bonded. In the present processes the upper band contacts the inner divider wall while the lower band contacts the exterior surface of the outer wall of the tubular container. In order to prevent the marring or otherwise putting a defect into the exterior surface of the outer wall the temperature of the lower band is maintained at a lower temperature than the upper band. This will decrease the temperature of the exterior surface of the outer wall and prevent imperfections in the exterior surface of the outer wall. The advantage is a multichamber tubular container without any imperfections in the exterior surface. This enhances the overall appearance of the tubularcontainer.
